The group cited an audio recording of Meraz criticizing the school's Multicultural Resource Center as being hostile to anyone who isn't black and making other comments disparaging black students. Meraz did not return a phone call Monday from The Associated Press.

The university's Chief Diversity Officer, Wes Pratt, says a student made an informal complaint against Meraz in December. He says the student has indicated she wants to make a more formal complaint and the investigation will continue. He would not give details of the complaint.
